Dick Clark's New Year's Rockin' Eve (NYRE), billed since 2008 as Dick Clark's New Year's Rockin' Eve with Ryan Seacrest, is a New Year's Eve television special broadcast by ABC. The special broadcasts primarily from New York City's Times Square and prominently features coverage of its annual ball drop event hosted by television personality Ryan Seacrest, along with live and pre-recorded musical performances by popular musicians from Times Square and Hollywood. Since 2016–17, the special has regularly included performances and coverage of midnight festivities from other U.S. locations, including New Orleans (Central Time, from 2017–2024) and San Juan (Atlantic Time, from 2021–2022).

Its creator and namesake was the entertainer Dick Clark, who conceived New Year's Rockin' Eve as a youthful competitor to Guy Lombardo's popular and long-running New Year's Eve specials on CBS. The special first aired on December 31, 1972; its first two editions were broadcast by NBC, and hosted by Three Dog Night and George Carlin, respectively, with Clark anchoring coverage from Times Square. In 1974–75, the program moved to its current home of ABC, and Clark assumed the role of host. Since 2000–01, the special has broadcast segments in prime time alongside the main late-night broadcast; initially occupying the 10:00 p.m. ET/PT hour, from 2011–12 onward the special has occupied the entirety of ABC's primetime and late-night schedule on New Year's Eve.

Following the death of Guy Lombardo on November 5, 1977 and the decline of CBS's specials, New Year's Rockin' Eve grew in popularity and became the dominant New Year's special on U.S. television. New Year's Rockin' Eve has consistently remained the highest-rated New Year's Eve special broadcast by the United States' major television networks; its 2012 edition peaked at 22.6 million home viewers—not including viewers watching from public locations, which were not yet measured by Nielsen at the time. The series has most recently been renewed through at least 2028–29.

Dick Clark hosted New Year's Rockin' Eve annually from 1973 through 1999 and from 2001 through 2004. For 2000, Clark participated in ABC News' day-long ABC 2000 Today telecast, joining overall host Peter Jennings for coverage from Times Square. In December 2004, Clark suffered a stroke, which resulted in Regis Philbin serving as guest host. Due to lingering speech impediments from the stroke, Clark ceded hosting duties to Ryan Seacrest the following year, but he continued to make limited appearances as a co-host until his death on April 18, 2012. Hosting solo since the 2012–13 edition, Seacrest was joined for the 2023–24 edition by Rita Ora as co-host and correspondent from Times Square, and Jeannie Mai as host of the Los Angeles-based concert segments.
